Because Microsoft was trying to takeover and change Java, and Sun actually made Java. How is that in any way the same situation as this?
Take over and change? They were adding functionality: embrace and extend. It wasn't like most reasonable people wouldn't agree it was lowercase "javascript".
Seems pretty similar to what's happening today.
So, is "X abuses IP law" hatred is out of principle or because folks seem to be in love with Sun and Google and hate Oracle and Microsoft.
